What's you traffic like? What's your niche? What's you URL to check if placement is OK? You need to provide more info so someone could help you.
It can also depend on your site's niche (how much the ad pays), you'll need to look at your CTR to determine that. A very low CTR may be fixed with better placement.
I was abt to start a topic like this before i see something like this,I my webblog,the hits is so poor that Oh God!you pity me if i show you my account. What can i do? Help!
Please provide a link and we will try to help ya. If you are talking about the china culture site, move the adsense to the top (where whats new is). Also instead of saying google ads, refer to them as sponsors. Also ad some text ads, you need to saturate your site with more well placed ads. You did do a good job blending the ads though, almost too well where people don't notice them, perhaps others may input on that.
